Next, under Qin Xiaohe's arrangement, Hao Shuang and the big murderer made a record separately - as the victims of this extortion case, their transcript will be direct evidence that the female stall owner and his gang were sent to prison.

Hao Shuang walked out after making the transcript, and found that the big murder sister had also finished the transcript and was standing in the courtyard waiting for him.

"Hao Da...... Brother, I'm sorry to implicate you in this matter, and thank you very much for helping me!" The big murderous sister blushed and handed a note to Hao Shuang, "This is the address of my internship in Tianbei City, I hope to come to me when I have time, I will invite you to dinner!"

Hao Shuang took the note and looked at it, only to see a line of words written on it: Zhao Yanfei, Chemical Department of Tianbei Minmetals Pharmaceutical Company. There is also an office phone number left at the end.

Oh, Minmetals Pharma?

Not a foreign trade company?

It does seem to be a beautiful misunderstanding.

I remember clearly that the strong woman named Zhao Yanfei works in a foreign trade company in the mainland!

If she is not a strong woman in foreign trade, she will not be of much use to herself. Such a tough girl, it is better to have less contact in the future.

"Okay, I got it!" he folded the note and tucked it into his trouser pocket.

"Brother Hao, I'm going to buy a train ticket to Tianbei tomorrow, I've been delayed here for so long, I don't know if I can buy it!" Zhao Yanfei stuffed the note, and hurriedly waved goodbye to Hao Shuang.

"Buy a train ticket for Tianbei, don't be afraid, don't be afraid! I'll send someone to take you over, and you'll definitely be able to buy it!" Qin Xiaohe listened to it on the side, and immediately called out a policewoman in the station and asked her to take Zhao Yanfei to buy a train ticket.

In this era, it may be difficult for others to buy train tickets, but it is not difficult for the police station in the jurisdiction next to the railway station square.

Yes?

The police station still has this function?

Hao Shuang's eyes suddenly lit up.

In this era, taking a plane requires a letter of introduction and a certificate from the unit, and the ticket buying procedure is also very cumbersome, and key flights are also very rare. So whether it's a business trip or a trip, the first choice is to take the train.

So today is really a blessing in disguise, through this incident and the police station, at least when you want to buy a train ticket in the future, you don't have to worry.

"Uncle Qin," Hao Shuang sent an invitation to Qin Xiaohe, "Director Lu of Tianyang Ceramics Factory will have dinner tonight, why don't you also go over with me and Director Sun?"

"Thank you!" Qin Xiaohe laughed and waved his hand at Hao Shuang, "Expert Hao, I understand your intentions." But it really can't be passed, according to our regulations, it is strictly forbidden to accept the party's invitation to eat during the case handling period. ”

Hao Shuang naturally knew that it was impossible for Qin Xiaohe to agree to go, he just revealed a piece of information to Qin Xiaohe through an invitation, that is, he said that in addition to Tianyang Special Ceramics Factory, he was also a guest of Tianyang Ceramics Factory. In this way, it will naturally be easier to deal with Qin Xiaohe in the future.

Qin Xiaohe kept sending Hao Shuang and Sun Guishan to the gate of the police station before shaking hands with them and saying goodbye.

There is a silver-gray Shanghai car parked next to the gate, which is Sun Guishan's factory director's special car.

"Expert Hao, I have been this Shanghai brand for some years, and it is definitely not as comfortable as Director Lu's Blue Bird King, I hope you will take care of it!" Sun Guishan personally opened the car door for Hao Shuang, and said with a smile while inviting him in.

"I'm a student, I crowd the bus every day, it's good to have a car to sit in, where do you pay attention to the Shanghai blue bird?" Hao Shuang sat in with a smile and said: "However, Director Sun, it's not too difficult for you to change a car, right?"

"How can it be so easy?" Sun Guishan sat in, patted the seat under his buttocks, and said: "No, I expect the replacement project of the porcelain support shaft device to be successful, and then apply to the superior with a cheeky face to get a new car!"

Hey, you're waiting for me here!

Director Sun, Director Sun, I didn't expect you to look at the thick eyebrows and big eyes, and there are so many twists and turns in your stomach!

However, Hao Shuang can also understand that Sun Guishan must have used a huge relationship behind his back in order to save him this time, so that Fang Yuanan, the leader of the Cuihu Police Bureau, brought the director of the Political Department and the secretary of discipline inspection to the scene in person, and even suspended Lu Yuebang for review on the spot.

In this case, if he has no way to help Tianyang Special Ceramics Factory to replace the porcelain support shaft device with the project, Sun Guishan himself will become a big joke because of today's actions.

It seems that he must come up with some dry goods for Sun Guishan to enhance his confidence!

Although the porcelain support shaft device belongs to a high-precision project in this era, but after 2000, it has faded its mysterious coat under the research of various high-precision instruments, and has become a very ordinary special ceramic product.

Hao Shuang, as a scholar of Xijiang Ceramics University, is naturally no stranger to the firing formula and firing process of the porcelain support shaft device, which is a special ceramic support device with high temperature and acid and alkali resistance.

Although it may be due to the age, he may not remember the exact ratio of the various ingredients in the formula, but the approximate proportion is still in his mind. As long as he gradually verifies according to the principle of raw material proportion, and finally finds the right formula, it is not too difficult to fire a qualified porcelain support shaft device.

"Director Sun, your factory has been tackling key projects for more than a year," Hao Shuang said with a smile, "How many kinds of production raw materials have you tested?"

Sun Guishan couldn't help but be shocked when he saw that Hao Shuang finally opened his mouth to talk to him about the technical problems of the specific porcelain support shaft device.

"Expert Hao, our factory has tested four materials such as alumina, silicon dioxide, zirconium dioxide, and silicon carbide as the main raw materials to prepare porcelain support shaft devices. Sun Guishan replied, "At present, the project research team of our factory tends to use alumina as the main raw material to produce porcelain support shaft devices. ”

"Alumina should indeed be used!" Hao Shuang nodded and said, "Alumina has the advantages of good chemical stability, high temperature resistance, corrosion resistance, high mechanical strength, and a wide range of sources, mature preparation technology and much lower price than other raw materials, and it is indeed the preferred main raw material for the production of porcelain support shaft devices!"

Sun Guishan couldn't help but be overjoyed when he heard that Hao Shuang was so precious about the advantages of alumina. It seems that he is really looking for the right person this time, and Expert Hao really has the goods in his stomach!

However, Hao expert, using alumina as the main raw material for the production of porcelain support shaft devices, also has many shortcomings that cannot be overcome. Sun Guishan expressed his worries, "Because the melting point of pure alumina is as high as 2,504 degrees Celsius, and the amount of liquid phase produced at high temperatures is very small. In the experiment, we found that if the alumina content reaches about 99% in the porcelain support shaft device, the sintering temperature is required to be at least 1,750 degrees Celsius, and if it is lower than 1,750 degrees Celsius, the fired support body cannot obtain sufficient mechanical strength and cannot meet the requirements of production design. ”

"However, such a high sintering temperature is quite demanding in terms of technology and cost for the production of support shafts. With the current technology of our special ceramics factory, although it can be successfully realized in the laboratory, it cannot be applied to actual production. ”

"In addition, if the content of alumina in the support shaft is reduced, although the firing temperature can be reduced, the mechanical strength of the obtained product will be greatly reduced, and the indicators in terms of acid and alkali corrosion resistance cannot meet the requirements at all!"

After Sun Guishan told the difficulties encountered by the research team, he looked at Hao Shuang with hopeful eyes to see if this genius college student, who could casually fiddle with the ceramic equipment imported from West Germany, could point out a way for them in the dilemma of the development of porcelain support shaft devices.
